The WorldExpo’10 dataset [1]} contains 1,132 video sequences that are captured from 108 scenarios and it consists of 3,982 annotated frames with a size of 576\(\times \) 720. The frames with the region of interest (ROI) are divided into a training set with 3380 frames and a test set with 600 frames. The test set consists of 5 five different scenes (S1-S5) and each scene contains 120 frames. For fair comparisons, we followed the methods in [1]} to generate the density map.
